Recording Interface

I think that one of the next steps for RockBox on coldfire-based players is
to get a recording-api up and running.

Here is a very basic list of what we need to do:

1) We need a way to get the encoding possibilities of each codec.
So that the user can choose between different bitrates, ....

2) We need to setup an interface for recording

3) We need to adjust the current recording interface.

4) We need to extand recording screen.

So if there any people haveing some time to look at the first point, it
would be nice.
I will also look at this topic and try to code something, but at the moment
the iAudio-port takes much of my time.
